WebThe Curtius rearrangement (or Curtius reaction or Curtius degradation ), as first defined by Theodor Curtius, is a chemical reaction that involves the rearrangement of an acyl azide to an isocyanate. [1][2] Several reviews have been published. [3][4] The isocyanate can be trapped by a variety of nucleophiles. WebIn organic chemistry, the oxy-Cope rearrangement is a chemical reaction.It involves reorganization of the skeleton of certain unsaturated alcohols. It is a variation of the Cope rearrangement in which 1,5-dien-3-ols are converted to unsaturated carbonyl compounds by a mechanism typical for such a [3,3]-sigmatropic rearrangement.. The reaction is highly …
